Heisenberg Group - Higher Dimensions

Higher Dimensions

More general Heisenberg groups Hn may be defined for higher dimensions in Euclidean space, and more generally on symplectic vector spaces. The simplest general case is the real Heisenberg group of dimension 2n+1, for any integer n ≥ 1. As a group of matrices, Hn (or Hn(R) to indicate this is the Heisenberg group over the ring R or real numbers) is defined as the group of square matrices of size n+2 with entries in R:

where

a is a row vector of length n,
b is a column vector of length n,
is the identity matrix of size n.

Famous quotes containing the words higher and/or dimensions:

    “You try to tell me anything about the newspaper business! Sir, I have been through it from Alpha to Omaha, and I tell you that the less a man knows the bigger the noise he makes and the higher the salary he commands.”
    —Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    “I was surprised by Joe’s asking me how far it was to the Moosehorn. He was pretty well acquainted with this stream, but he had noticed that I was curious about distances, and had several maps. He and Indians generally, with whom I have talked, are not able to describe dimensions or distances in our measures with any accuracy. He could tell, perhaps, at what time we should arrive, but not how far it was.”
    —Henry David Thoreau (1817–1862)
